+Summary: mono produces incorrect arithmetic result
+
+Description of Problem: 
+ 
+With the default optimizations for x86, mono produces the incorrect result 
+of "50" for the program below: 
+ 
+using System; 
+ 
+public class A { 
+    public static void Main () { 
+        A a = new A (); 
+        a.Test (); 
+    } 
+ 
+    public void Test () 
+    { 
+        A a = new A (); 
+        // the following is the problematic line 
+        _intValue += a.Value + a.Value / 2; 
+        Console.WriteLine (_intValue); 
+    } 
+ 
+    private int _intValue; 
+    public readonly int Value = 100; 
+} 
+ 
+However, when mint is used or mono is used with -O=all, the correct number 
+"150" is produced. This occurs independent of the C# compiler used (mcs or 
+csc) 
+ 
+Steps to reproduce the problem: 
+1. mcs test.cs 
+2. mono test.cs 
+3.  
+ 
+Actual Results: 
+ 
+Prints "50" 
+ 
+ 
+Expected Results: 
+ 
+Prints "150" 
+ 
+ 
+How often does this happen?  
+ 
+Always 
+
